Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.

Learners observe the animated operation of an astable mulivibrator using a 555 IC (integrated circuit) chip and external components.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

In this animated activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.

In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.

Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.
